METHOD OFAND MEANS FOR PRODUCING'PATTERNS UPON PRINTING-BLOCKS.

SPECIFICATION forming part of Letters Patent No. 274,944, dated April 3, 1883. Application filed November 8,1882. (No modell To all whom it may concern Y Be it known that I, ANDREW JACKSON, of Chester, Pennsylvania, have invented certain Improvements in Methods of and'Meaus for Producing an Ornamental Design or Pattern upon Oil-Cloth Printing and other Printing Blocks, of which the following is a specification.

An oil-cloth printing-block, as is well known, is made of a large rectangular or other shaped piece of wood-such as box-wood, maple, or the like-which is usually eighteen inches square, and the lower surface or printing-face of which is first made perfectly level, and is then scored or inout transversely in two directions, after the manner of a checker-board pattern into a very large number of squares, technically called pins,7 pegs,7 or shapes,77 each of which is, for instance, a twelfth to a sixteenth of an inch square upon its operative surface.

rlhe pattern is produced' by chipping outcertain of the pegs and leaving others untouched to constitute the ornamental printingsurface proper.

H eretofore these fainting-blocks, scored and in readiness to have the pattern marked upon them, and to be then chipped or engraved in Vaccordance with such pattern, have had the design or pattern printed upon them by hand without the aidl ot' any mechanical contrivance. A paper pattern of one-quarter the face area of the block--say, nine by nine inchesmarked or laid oli' in a manner correspondent with the scorings on the block and painted with thedesired design, is then laid beside the block, and the blockcutter is compelled to transfer by hand, laboriously and by careful measurement, all the markings of a certain color on the pattern to the block, four times reproducing all the markings of a certain color on the paper-pattern on the block.

The object of my invention is to obviate this quadruple manual transfer from the pattern to the block, and to enable the block-cutter to transfer to one quarter orother predetermined fractional face area of the block all the markings of acertain color on the pattern, and to then mechanically and without further artistic hand transfer print the remainder of theblock with the pattern.

The above object I accomplish by the practice of a method and the use of eontrivances of the character hereinafter described and claimed.

In the accompanying drawings, I have represented a preferred form of apparatus for the convenient practice of my invention,and have illustrated the practiceof the method invented in itsV various stages as well as it is possible to do by means of pictorial illustra-tions.V

l lirst take an oil-cloth printing-block ofthe usual character, a plan view of the operative face of which is represented in Figure l, an .end view in Fig. et, and a more exact view of the scorings of which is represented in the partial plan view ofFig. 2, and,further, take apainted paper pattern (represented in Fig. 3) of onequarter the face area of the block, and, laying the pattern beside the block, mark conven iently, by water-color paint, upon acorresponding portion of the block, in any preferred manner, such portions, a, forinstance, of the pattern of Fig. 3 as are represented by vertical shadc-lines in said pattern, with the result that `block so 'marked is then, to the extent of the' area marked, chipped out or engraved as to the pins or pegs not marked, with the result that only the marked pins of the marked area remain. fllhe'appearauce of the marked and engraved portion of the block in this stage is represented in Fig. (i, and designated by B, the portions D of the block represented in solid black being theportions from which the pins have been chipped, and the portions (t in shaded lines representing the marked pins which remain. rlhe block so engraved as to a quarter of its area (it is to be remembered that while I speak in terms of quarter-areas, the invention may be practiced with respect to any fractional other than quarter-areas) is in readiness for that mechanical transfer by which the design ofthe marked portion is to be trailsferred to the other portions which have not Vbeen marked, and by which the artistic hand transfer of the design heretofore essential as to the entire surfaces of the block is obviated as to all portions, save that frictional portion, which is engraved.

IOC

The mechanical transfer is conveniently effected in the following manner:

c, Figs. 9, 10, 11, 12, and 15, is a prepared pad or table covered with cotton, s, or other fit material, stretched over an interlining, w, to which ink or other suitable transferable pigment will adhere. The table is preferably of larger face arca than the block square and provided with a fixed gage, d,extending across one side. The fixed gage is equipped with gage-studs c, as shown in the drawings.

The above-described` padded table is well suited for thecarrying out of my invention. I do not, however, desire to restrict myself to the precise construction of padded table represented and described, as it will be obvious that many other prepared receptive surfaces which are not strictly padded tables may be employed with equal profit for the carrying out of the mechanical transfer hereinafter set forth.

The first step of the process is to coat the engraved portion ofthe block, or that portion represented in Fig. 6 by B, conveniently by means of an inking-pad,f, represented in side elevation and in top plan view in Figs. 13 and 14, ,with such suitable ink or pigment as will readily transfer; to further apply afalse or removable gage, g, against the Iixed gage upon the face ofthe table in the manner represented in Fig. 9, and then to apply the block of Fig. 6, coated with the transferable ink or pigment, against the false gage, face downward, upon, for instance, the right-hand lower portion of the table in the manner and position represented in Fig. Q-that is to say, so as to bring the engraved portion B of said block over that quarter-area of the table which is designated lby C in Fig. 12. The block is gaged to this or any other predetermined position upon the table by means of gage-studs h upon the false gage and other gage-studs or adjusting devices, t, applied to one of its sides. The block, applied as above to the table, is tapped or pressed firmly'down thereupon until its engraved portion B produces upon the area C of the table its exact imprint in paint. Upon the lifting of the block from off the table this imprint, in a tacky condition, remains on the surface O of the table. The block is then replaced upon the table in the position represented in Fig. IO-that is to say, in such position as will bring its engraved portion B, Fig. 6, upon the lower left-hand portion of the table, (the area marked l) in Fig. 12,) and as will bring its upper quarter portion (marked E in Fig. 5) in exact alignment with the tacky im'- print upon theright-hand lower portion C, Fig.

12,0f the table, so as to reproduce such imprint upon the left-hand upper quarter, E, Fig. 5, of the block in the manner indicated by the shaded lines ot' the area marked F in Iiig. 7.

, After the block has been lifted from this, its

second, position the false gage is removed from the table and the block is again applied to the table against the fixed gage in the position represented in Fig. l1, which is the third po sition of application. In this third position the tacky imprint which has been produced across the entire lower portion ot' the tablei'. e., across the two areas marked G and I) in Fig. 12-by the application of the block in the two positions of Figs. 9 and l0, will come in exact alignment with the lower halt' portion of the face of the block, or that portion which is represented by the letter G in Figs. 5, 6, and 7, and which is not vet printed in the representation of the partially-printed block ot' Fig. 7, and will print or transfer itseltl upon 'said lower portion G of the block, with theresult that said lower portion of the blockthat is again to say, its two lower quarters-will bc simultaneously printed with the design and caused to assume the appearance represented by the area marked H in Fig. 8.

By the above-described means the entire design of the pattern has been mechanically transferred upon three-fourths of the entire face area'of the block, and all that remains to be done to fit the block for printing is to engrave or chip out the pins or pegs not imprinted with the design.

In Fig. 12 is represented the appearance which the printing-table assumes after the three applications of the block, showing how its :entire surface receives the imprint of the pattern. l

Any desired construction of table may be resorted to, that represented in the sectional View of Fig. 15, which is taken on the, line .fr x o1' Fig. 12, being convenient, the construction represented being, as hereinbefore stated, that of an intermediate lining between the material ot' the table and that of its covering.

The pigment or ink employed to eifect the transfer may be applied to the engraved quarter of the block by other means than the inkin g-pad represented-was, for instance, by brush or inking-rollcr-and the application may be renewed before each subsequentapplication of the block to the table.

That arrangement of gages which I have represented is a convenient one; but other gaging devices or contrivances for securing exact registry or alignment of the areas to be brought in contact may be resorted to Without departure from my invention.

It is advisable in the practice of my invention with different designs to have a separate printing-table for each design, so that should any of the transferringink remain fresh upon the table in a given pattern, the possibility of imprinting the wrong peg may be avoided.

As heretofore stated, the invention is applicable when other areas than a quarter are employed. Thus, for instance, an eighth of the face of the block might be engraved, if the pattern permitted it, and the transfers made by the employment of three false gages and a larger number of applications ofthe block. I regard the quarter-division as the quickest, best, and most advisable, because IOC) IIS

rrr

the present practice of preparing paper patterns of oil-cloth designs isto embrace either the whole design or a quarter part of it on said pattern.

The same care in the application and gagi ing ot' the block upon the table is to be exercised in the practice of this invention as would be exercised in the printing of oil-cloth fabric with the block. i

The method of transfer is of course applicable in blocks which are not scored or inout, but which are manually engraved by means of carving-tools or gravers implements, the practice of the mechanical transfer of a preparedand cut area ot' block to `another area not prepared remaining the same, whether the block be a scored one and engraved by chipping or one having atrue surface engraved by actual section.

Having thus described my invention, l claim-'- A 1. The method of producing an ornamental design or pattern upon an oil-cloth printing or other printin g block hereinbefore described, which oonsists,rst,in engraving or otherwise providing a given area of the block with a predetermined design 5 second, in coatingthe my name this 25th day ofOctober, A. D. 1882.`
